Megaflint Keyless Entry Door Lock Deadbolt Keypad Mechanical Stainless Steel (Pass Code or Key) 100% Mechanical, No Electronic

Pro:- Easy to setup.- No battery, no WiFi to worry about disruption.- Solid. Nice looking.Con:- Normally, when you open a door, turning left to open (visually moving the the locking stem to the left) and turning right to close (moving the stem to the right to engage the stem into the door jamb). However, this lock is opposite. Left to lock and right to close. This is a major troublesome confusion. Hope the manufacturer should take this into consideration and revise it.

Very easy to install with a bit of patience. Used on an inwards opening door that are original to my 1885 built home. The other reviews diss on the lock itself too much rather than their own installation tactics or drill holes/door function.If you are looking for a solid lock, that is to protect something serious, don’t opt for this. Spend bigger, these are very easy to pick. In situations like mine, to keep roommates out of your room without taking keys everywhere, works perfectly. Not recommended for exterior/outdoor locks for this reason.In my opinion, well worth the $70. But I only recommend it for an interior door and if it’s not a serious situation, more of a deterrent. Locks only keep out the honest people.

it was really easy to change the password - and easy to install - works like a dream and I didnt need to wire it into electrics and doesnt use batteries - just purchased another one for the garage side door

Nice lock. I install dozens of lock every year.Pros: no batterySimple installationCons: right hand lock only. To install left hand, you would have to flip the deadbolt. Doing so may leave a noticeable gap on the inside, as the inside rosette is smaller than your typical lock.Also the combination is good to accessing common area, but for something more private, you would want a digital lock with a battery. You just have to punch any of the 6 corresponding keys to unlock the door, there's 12 keys total, so probability-wise, it's not 8000 unique combinations. It's actually 1/4148 chance of unlocking your door. To put that into context, the chance of guess a 4 digit code in the correct order would be 1/10,000. Or a 6 digit code in the correct order would be 1/1,000,000.Also because I had to install this on a left hand door, you have to turn the knob in the opposite direction that you normally would with a standard lock. That caused me to graze my knuckle on the number pad and made a small gash.Overall, I like the concept alot. I will be returning these specific mechanical lock for another brand on Amazon. I'm going to use these locks in common areas of my rental property.

The product is good.Just what I was looking for.Install would have gone smooth, except this looked like a defective return.Keys were not in the correct slot, screws were not in the package, missing two screws and had one extra screw, worse is the latch was bent. looked like someone tried to install it, and pounded on it.I managed to fix it as best as possible, and it works 90%.It took long to arrive, and I couldn't wait for another.Who ever the seller is, is nothing but a crook, selling defective returns.
